Usages

import readlammpsdata as rld

# 0. read Atoms, Masses etc.
Atoms = rld.read_data(lmp, data_sub_str = "Atoms # full")
Masses = rld.read_data(lmp, data_sub_str = "Masses")
PairCoeffs = rld.read_data(lmp, data_sub_str = "Pair Coeffs")
Bonds = rld.read_data(lmp, data_sub_str = "Bonds")

# 1. read box size
xyz = rld.read_box(lmp)
Lx = xyz["xhi"]-xyz["xlo"]
print(xyz)
print(Lx)

# 2. read atomic number 
Natoms = rld.read_atom_info(lmp,"atoms")
print("Number of atoms is %s" %Natoms)

# 3. read charges 
charges = rld.read_charges(lmp)
print("Charges of atoms are %s" %charges)
print(round(sum(charges),6))
# 4. ......
print(help(rld)) # for read all functions
